Speedmaster 3570.50

The Omega Speedmaster 3570.50, known as the "Moonwatch," is cherished for its direct lineage to the chronographs worn during NASA’s Apollo missions. Collectors value this reference for its adherence to the classic Speedmaster formula: hesalite crystal, manually-wound movement, and the iconic black dial layout. Its 42mm case and lyre lugs give it wrist presence without sacrificing the vintage proportions that made the Moonwatch famous.

This reference houses the Caliber 1861, a manual-wind movement celebrated for its reliability and historical continuity. Compared to earlier references like the 145.022, the 3570.50 offers modern production quality while staying true to the original design. The hesalite crystal (as opposed to sapphire in later variants) and solid caseback are key collector draws, as they mirror the specs of the models certified by NASA for spaceflight.

Price variation is driven by condition, completeness (box, papers, original bracelet), and production year; earlier 3570.50s with tritium dials (pre-1997) are less common and command a premium. Later models feature Super-LumiNova, which glows brighter but lacks the vintage patina. When buying, confirm the presence of the correct "dot over 90" bezel on earlier examples, as replacements can affect value. This reference is a mainstay for anyone seeking an authentic, wearable piece of space history with strong collector interest.
